- Reduce the number of elements for which response is computed by using "Define > Bridge Loads > Bridge Responses" or "Bridge > Bridge Response" menu command by specifying smaller groups than ALL. Please see the "Moving Load Case Results Saved" form below.
- Use a coarser Lane Discretization lane discretization.
- You could also use quick method of response calculation for moving load analysis. This method is described in CSI Analysis Reference Manual, chapter "Bridge Analysis", section "Moving Load Response Control > Exact and Quick Response Calculation". Please see the "Moving Load Case Results Saved" form below.
